propeller shaft coupler against transmission out-
put flange. Shoulder on propeller shaft coupler
should engage recess on transmission output
flange face with no resistance.
NOTE: Some propeller shaft couplers may not have
a shoulder on mating face. On these installations,
use a straight edge to check centerline alignment.

engine bed) and move engine, as required.
Tighten lag screws securely.
c. After engine has been properly aligned:
Tighten engine mount nuts securely, and be
certain to bend one of the tabs on the tab
